Huron-VALVE.

To all whom t may 00m/cem:

Be it known that I, AXEL'G. J. RAPP, a

citizen of the United States, residin at Chicago, in the county of Cook and tate. of Illinois,'have invented a certain new and useful Improvement in vHutch-Valves, of which the following is a specification.

My invention relates to improvements in hutch valves such as are used in connection with the well-known type of FoustV jig for coal washing. YIt has for one Object to provide a new and improved form ofv valve which can be easily Operated, ositive in closing, subject to a minimum O wear and will be easily and cheaply renewable when finally worn out.

My invention is illustrated more or less diagrammatically in the accompanying drawings wherein Y Figure -l is a sectional view ofl a part of a jig showing my device'in place.

Fig. 2 is a plan view of the valve seat and holding socket.

F Fig. 3 is a section along the linej3-3 of i 2. l v v ig. l is a side elevation of the valve and valve stem. y

Like parts are indicated by like characters in all the figures.

A is the hopper of a Foust jig adapted to contain water as indicated, and have at the bottom an accumulation of the heavy fines from the coal or other material being washed. A1 is a valve seat assembly, A2 a valve carried by a valve stem C, whereby the fines may be permitted to run off. l There is nothing novel about the idea of treating the fines in this manner. My invention lies in the valve itself and the valve seat.

B is the supporting cup or socket or valve base rigidly mounted at the bottom of the hopper; it may be cylindrical or preferably, as here shown, square. B1 is a ledge extending inwardlyv about the entire inner periphery of the socket. B2 is a valveplate inolosed within and tting the socket and resting upon the ledge. The weight of the seat itself and of thecontents of the hopper keeps the seat in position On the ledge in the socket.

y The valve seat'has a circular aperture Bs therethrough bounded by two frusto conical surfaces B4 Bfs as indicated, the surfaces being chilled or otherwise hardened and berApplica'don'iled January 27,1919. Serial No. 273,278.

Specification ofLettersPatent. I Pateuljlited Sept. 20,

ing adapted-to act interchangeablyas valve seating surfaces, softhat when one is worn out the valve seat may be turned over and the other surface may thenvbe used.

i C is a valve stem and has, at `the upper end, a suitable manipulating-handle C1 and at its lower .end it carries the-valve. This valve is made 'up of a cylindrical portionCz,

on either side of it a frusto conical Vportion Y C3 C4, and on both sides'of thefrusto conical portions smaller cylindrical portions C5. All these parts mayl be made-separate and strung upon the rod or ma be one'integral casting placed upon the ro in either event,I f'

drawn up rigidlyagainst the'shoulder C 5 by a nut -C7 so that when one of the conical members wears down the valve assembly may be taken off and. the other substituted It will be evident that while Ifhave shown in my drawings an operative device, 5 still many changes might'be made in size, vshape and arrangement of parts without'. departing -materiall from the spirit lof'myinvention.

I wish t erefore that my drawings be regarded as ina sense diagrammatic.l

The use and operation if my invention are Vas follows The valve is operated'in the usual manner by being Opened at certain predetermined times to permit the fines and a minimum of water to run out. It is then seated. The

constant movement of the valve and they abrasion by the fines both when the valve is open and when it is seated, gradually wears away the valve and valve seat, and, of course, this wear will be more or less irregular. The valve will soon commence to leak.

When the leaking becomes too great to be permissible, it is necessary only to stop operations, lift up the valve, lift out the valvev reciprocate toward andefrom the' plate to` open and close the aperture, and a partasso# ciated with said member and adapted' at allY open andk close the aperture, and a part associated with said member and adapted at all times to project beyond'the plate.

2.*A vhutch valve assembly, comprisinga-V tubular socket, a shoulder therein, a flat apertured valve plate resting loosely upon the shoulder, a valve member adaptedA to times toproject beyond the plate, the valve ,and valve seat being so .positioned .thatthe fliquid pressure tends to hold the valve seat fthe shoulder, a 'valve member adapted to;

on the'shoulder and the valve on the valve seat. v

tubular socket, a shoulder therein, a flat apertured -valve plate resting loosely upon reciprocate toward and from the platev to open and close the aperture, and a-partassociated' with said memberand adapted at all Atimes to project beyond -theplate, said valve member comprising a recprocable stem, ,al

cylindrical portion v of greater diameter than the aperture, two conical .portions whose bases are of the same diameter as the larger cylindrical portion, and two cylindrical portionssmaller vin diameter than the aperture,`

and binding the smaller truncated ends of the conical portions. l f 4. A hutch valve assembly, comprising a tubular socket, a yshoulder therein, afiat apertured valve plate resting loosely upon the shoulder, a valve member Vadapted to reciprocate toward and from the plate to open and close the aperture, and a part asso- 3. A-A hutch Y'valve' assembly, comprising ay ciated with said member and adapted Vat all times toV project beyond the plate, the Valve and valve seat being so :positioned that the liquidVV pressure tends to hold the Valve'seat on the shoulder, and the valve on the valve seat, said valve member comprising a reciprocable stem, a cylmdrical portion of greater diameter than the aperture, two

conical portions whose bases are of the same l`diameter as Y rthe larger cylindrical portion, and two cylindrical portions smaller in diameter than the aperture, and binding the.

smaller truncated ends of the conical portions.` Y Y f 5. lIn a hutch valve lassembly a relatively large discharge passage, a relatively thin l flat apertured plate held therein, the aperture being much smaller in cross section than the i passage, y a valve mounted for. reciprocation toward and from the plate to'open and e the valve forguiding and directing material` which tends'to seat itself about Ythe Valve, and for forcing such materalaway to prevent withdrawal ofthe valve.
